T o all whom it may concern.'

Be it known that I, RICHARD E. MEYER, a citizen of the United States of America, residing at Detroit, in the county of Wayne n, have invented ce1'- tain new and usefn Improvements in Explosive-Engines, of which the following is a specification, reference being had -to the accompanying drawings.

In the operation of explosive engines of the sleeve valve type, or those using reciprocable or rotary split compression shel s, sleeves or rings, it is essential that some means be employed at the split or separable edges of the sleeve or shell, to prevent the escape of compression from within the cylinder of the engine. Inpositively confining the com ression within the cylinder of the engine,

riction between the sleeve or shell and the piston or engine block is reduced to a minimum, and the eiliciency of the engine materially increased.

The primary object of my invention is to provide a novel packing member or mem- Vers that may be readily located at the split or se arable edges of a sleeve, shell or ring to a ord one or more transverse partitionsv 1n the space that 'may exist between the con-- fronting edges of the split sleeve. In certain forms of the packin or partition menibers, said members are Xed relative to one edge of the split sleeve and are movable in the opposite edge thereof, while in another form of the packing, the member or parts thereot possess resiliency and has an inherent tendency to constantly pack the variable space between the confronting edges of a s lit sleeve.

Vnother object of my invention is to provide simple and eilective means iorestab lishing a driving relation between a rotary cylinder'.` sleeve, shell or ring' and operating mechanism therefor, and this feature oi' my invention may be considered as an improve ment in connection with my prior Patent No. 1,188,297, ot June 20. 1916. wherein there is disclosed a Sleeve valve that has split interlocking edges and novel means of attaching said sleeve valve to a gear or driving device. The proscrit invention may also be considered as an improvement. in conncc` tion With my enginc disclosed by my application Serial No. 91,564. filed April 17. 1916.

The present inventionn will be hereinafter specifically described and then claimed, and` reference will now be had to the drawings, wherein- Figure 1 is a vertical'sectional vien7 of a portion of an engine, provided with one form of packing member;

Fig. 16 is a perspective view of one of the packing members shown in Fig. 13; and

Fig. 17 is a similar view of one of the packing members shown in Fig. 7.

An engine in accordance with my invention may include one or more cylinders. but for an understanding of the present invention there is shown a single cylinder or block 1 having thc upper end thereof provided with opposed ports 2 communicating with the chambers 3. and below said chambers is a conventional form of Water jacket 4. The 'upper end of the cylinder is closed by a head horizontal sectional view of the 5 and the lower end thereof is opened to communicate with a crank case 6.

Rotatable in the cylinder 1 is a sleeve valve 7 which has the upper end thereof ported, as at 8, to communicate with the ports 2 of the cylinder 1. The lower end of the sleeve valve extends out of the lower open end of the cylinder 1 and is provided with a horizontally disposed gear wheel or circular rack having hub portions 10 and 11. The hub portion 10 extends into an annular recess 12 provided therefor in-the lower end of vthe cylinder 1, and loosely surrounding the hub portion 11 of the gear 9 is a cap or retaining ring 13 bolted or otherwise connected lto the cylinder 1, as at 14. The cap or retaining ring 13 supports a coupling ring 15 provided with a plurality of radially disposed lugs 16 extending into notches or recesses 17 in the lower end of the sleeve valve 7 and notches or recesses 18 in the hub portion 11 of the gear 9. The coupling ring 15 therefore establishes a driving connection between the gear 9 and the lower end of the sleeve valve, and as amodification of said driving connection, there is illustrated in Fig. 3, a sleeve valve 19 which has its lower en( provided with a plurality of radially disposed set screws or projecting members 20. These set screws or projecting members are adapted to extend into radially disposed openings 21 ii the hub portion 22 of a gear 23.- The gear 23 is devoid of an upper hub portion, but has a. lower hub portion surrounded by a cap or retaining rin 24 suitably connected to the cylinder o the engine. In either instance, the gear 9 or 23 meshes with a worm 24.EL operable in an offset portion 25 of the cylinder 1, said worm being suitably driven from the main crank shaft of the engine.

The sleeve valve or slot in alinement of the sleeve valve, ting of expansion sleeve valve during 7 has a` longitudinal slit with one of the ports 8 said slit or slot permitand contraction of said rotation in the cylinder 1. For one form of packing the slit or slot has its confronting faces concaved, as at 27, and beveled, as at 28. The concaved wall of the sleeve valve borders on the inner wall of said sleeve valve so as to form feather or posed to form a flared or inwardly tapered entrance into the groove having for its walls theconcaved walls -27 of the sleeve valve. By referenceto Fig. 1. it will be observed that the concaved and beveled walls extend from a. point in proximity to the port 8 to a polnt set in some distance from the lower end of the sleeve valve and at .'the ends of the concaved and beveled wall there are transverse slots 30. These slots are adapted to receive heads 31 of a compressible and expansible packing member The memsunk and xed inthe ber 32, asbest shown in Figs. Gand 8 is substantially semi-cylindrical and has its longitudinal edges fiared to provide outwardly or angularly disposed flanges 33.

he ends of the member 32 intermediate the sides edges thereof, have necks 34 welded or otherwise fixed to the heads 31, as shown in Figs. 6 and 7, so that while the heads 31 hold the member between the confronting faces of the split sleeve valve yet the side walls of said packing member may be distcnded or retracted as the sleeve valve einl pands and contracts during theoperation of the engine. The semi-cylindrical portion of the packing member is adapted to engage the conoaved walls 27 of the sleeve valve and by engaging the `feather or knife edges 29 seal any gap that exists between the feather edges of the sleeve valve. The more that the sleeve valve contracts, the closer the feather edges are brought together, the greater will be the sealing power of the packing member` 32, since said member will be crowded between the confronting faces of the sleeve valve. As said valve tends to expand, the flanges 33, which are normally out of engagement with the beveled faces 28 contact with said beveled facesand the resiliency of said packing member is sufficient to maintain the semi-cylindrical portion of the packing member constantly against the concaved wall 27 of said sleeve valve, and thus pack the gap or space between the confronting faces of the sleeve valve. The feather or knife edges 29 of the valve will be wiped by a piston 35 reciprocable in the sleeve valve, and with said sleeve valve under its maximum or minimum expansion, the piston contacts with the packing member 32, and there is no danger of the compression within the sleeve valveescaping past the piston.

Reference will now be had to Figs. 9, 10 and 14 showing another form of packing member. A sleeve valve 26 is slitted or slotted similar to the sleeve valve 7 and the confronting faces of the split sleeve valve are provided with opposed transverse and equally spaced slots 36 adapted to receive blades 37 carried by one or more -members 38, said members and the blades 37 being cut, stamped or pressed from sheet metal with the blades disposed substantially at right angles to the members 38,. The blades 7 are positively held at an angle to tire members 38 b portions 39 thereof, and to hold the mem er 38 in position relativeto the split sleeve valve, said sleeve valve has a seat 4U. The member 38 may be counterseat '4 0 by screws 41 or other fastening means, thus ositioning the member Hush with the perip ery of the sleeve valve andthere is no danger of the walls of the cylinder 1 being sooredor injured by the packing member during the ro: tation of the sleeve valve in its cylinder compression is therefore confined between the blades 37 should a gap or s ace exist between the confronting faces o the-split sleeve valve.

The form of packing membershown in Figs. 11 and 17 consist of a plurality of independent or single blades or partitions 42 that are placed in opposed slots 43 in the confronting faces of a split sleeve valve 44. It is preferable to fix the ends or partitions 42 in the slots 43 in one face of the sleeve valve 44, and allow the opposite ends of the blades or partitions to extend into and slide in the slots 43 in 'the other face of the split sleeve valve, during the expansion and contraction of said sleeve valve. The blades or partitions 42 may be erfectl fitted, as to size vfor the slots 43 1n whic they are to be fixed and the fixing may be accomplished by brazing or using some suitable securing means. For instance, as shown in Figs. 12 and 15, the ends of the blades or partitions may have apertured lugs 45 seated or countersunk in the periphery of a sleeve valve 47 and screws or other fastenin means 48 maybe employed for securing tlie lugs to the sleeve va ve A combination of the packing members is shown in Fig. 13, the combination consisting of s aced blades or partitions 49 and short lengt s of packing members 50 similar to the member 32. The blades or partitions will positively prevent compression from traveling lengthwise of a sleeve valve 5l in which the combination of packing members are placed, and the short packing members 50 operate similar to the long member 32.

To insure easy rotation of the sleeve valve in the engine cylinder, each sleevevalve has its periphery provided with spiral grooves or lubricant ways, 52, the spiral formation of which is interrupted at the split of the Veo sleeve valve, but during the rotation of the valve in either direction, with the grooves accordingly disposedthe grooves pliek u or receip a lubricant from one anot er. e main /supply groove is circumferential of the sleeve valve and is designated 53, said groove communicating with .a port 54 in the cylinder 1 through which the lubricant may be forcibly fed. ,To lubricate that ortion of the sleeve valve in proximity to tile port 8 or the upper end of the sleeve valve there are angularly disposed grooves 55 and lubricant is supplied tokthese grooves, from the grooves 52 during rotation of the'. sleeve. The lubrication of the` sleeve is facilitag, particularly in connection with the constr tion shown in Figs. 9, 10 and 14 since the of the bladesinder, of a rotatable sleeve valve spaces designated 39* afford lubricant pockets, said spaces bein the length ofthe s eeve valve. Whi e rel` ferring to these figures, particularly Fig.-9,4

wherein a piston with piston rings.V is shown in the sleeve valve, it will be noted that the space of the blades 37 is such that one or more of the iston rin s are bound toseal the piston re ative to ne sleeve. valve.l In' other words there is alwa s one or more piston rings between the b ades durin the practically thrbii hout reciprocation of the piston within the s eeve valve.

I am aware of sleeve valves having inter' rohi it the turning down or mach in the valves for perfect fitting in a devoid of tongues and practically uninterru ted.

t is thou ity of the s eeve Valves in accordance with my invention may be apparent without fu'rht that the operation and util- Y ther description, and while in the drawin s there are illustrated the preferred embo iment of my invention, itis to be underst'bod that the structural elements re susceptible to such variations and modifiliations as fall within the scope of the appended claims.
